I have a requirement that the first item in the combobox be a link button that says "[Add New"] and which will do additional action. How can I have the first button as a link button but the rest of items as regular static items. I have tried for days now and can't figure it out.
I would suggest you to refer to this documentation article, demonstrating how to add templates at design time. You could use the approach, demonstrated to instantiated the templates for each item, by to apply it only of the first one. I have prepared a sample page for you, demonstrating the implementation of the above suggestion.
